To all whom it may; concern:

Be it known that I, Gnome F. DILLIG, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, a citizen of the United States. have invented or discovered certain new and useful Improvements in Loading Mechanism, of which improvement the following is a specification.

The invention described herein relates to certain improvements in loading mechanism, especially to the class or type used in confined places, as mines or tunnels, and has for its object a construction in which the scoop moves in the arc of a circle. with which the surface from which the material is to be removed, is tangentialor approximately so said are o1 movement passing in such proximity to a receiving hopper that by the movementof the scoop around a second axis,

the material may be discharged into the receiving hopper. The invention hereinafter more fully described and claimed.

In the accmnpanying drawing forming a part of this specification, Figure 1 a side elevation of a loading mechanism embodying my improvements; Fig. 2 is a top plan view of the same. the transfer mechanism being omitted; Fig. 3 is a detail view of the reversible mechanism employed for moving the scoop; and Fig. 4 is-a sectional elevation on an enlarged scale, the left half being; on a plane indicated by the line and the right half by the line y 1 Fig. 1.

In the practice of the invention, a hot; shaped structure 1 is n'ionnted on axles 2. having wheels 3 adapted to move along rails 4. The box has an open top and is provided with, adjacentto its front end, a circular truck 5 on which is mounted the annular base (l of the boom or out-ringer 7. Suitable means. such as a sectional ring- 8 can bc c1n or out-ringer in position on the. track. Provision is made for the rotation or lateral shifting of the boom by any suitable means, such, as for cxan'iple, that shown, consisting of a driven pinion 9 inlcrmcshing' with teeth formed on the periphery oi the sectional clamping ring 8. At a suitable distance from the outer or free end of the boom, is mounted a shaft 10 on which are secured the upper ends of arms 11 and also a sprocket wheel 12 for rotating the shaft, as hereinafter described. In suit able hearings in the lower end of the arm 11 is mounted a hubs 1 ladapted o sproehet wheel I? is aiso connected 13 and is operativclv connected by 18 to the sprocket aheel on shai that by the rotation of the latter, i may be rotated as h The movement in the scoop around axis of the shaft .llis eii'ectei by means in wire ropes and 247-, passin in opposite directions around i 't'lllilrl 22. e ment of the scoop forward material, will meet with coi'isiderable rebat ahce, it is preferred that the pull necessary to eiiect such scooping" movement shonl i applied to both out of the shaft 13. that there will not be any twis oi the nism, when gathering material. in Fig. 2, the front portion of the Y divided, said parts being co) nee shaft 13 and pass around guuiep 2i and 25, i'nonnted on the boom, the ropes are brought to form a single str:

winding drum. As thci so once to the movement 1;

changed to a. position to discl box or body of the ear, sin

he sutiicient. This rope passes 'l of the shafts eve uit pulleys and 29, on to the winding drum. 19 and 20 are wound in oppo rated to wind up one of the ropes, roptcwill be let off the (rum at an rate.

the pinion loo 7 32 and interinesh u (In ti also ll'liliuc When 2.3

on the shafi'v pinion 36 on. the shaft shaft is keyed a pinion with the gear-Wheel -30,

. or the pinion at loosel .shaft 32 and inter-meshing with the pinthrough the pinion 35, the gear-wheel 30 will rotate. in the opposite direction from that imparted to it by the pinion 31.

The rotation of the shaft 10 whereby, through the medium of the sprocket wheels 12 and 17 and the chain 18, the shaft 13 is rotated to turn the scoop, is clfected by a sprocket wheel on the shaft 39, a chain 4:0

10D. on the shaft 37. On this same shaft 37, is keyed a pinion 4-6 adapted to intermesh with the gear-wheel 42. By shifting i the chit eh 43, into engagement with the pinion 44, the direction of rotation of the pin ion 42 is reversed and through such reversal, areverse turning movement of the scoop is also effected.

The car and parts carried thereby, having been shifted into suitable relation to the ma terial to be loaded, the scoop is turned to the position shown in Fig. 1. The drum 22 is then operated so as to draw in the rope 19, thereby causing the scoop to move forward to gather up material in the arc of the circle around the axis of the shaft 10. At the same time, or shortly after, the scoop has begun to move around the axis of the shaft 10, the shaft 13 is rotated so that the scoop will turn toward an upright position, so as to retain the gathered material. These movements of the scoop around the axes of the shaft 10 and 13 may be effected simultaneously or the movement around the shaft 10 may be started somewhat before the movement around the shaft 13 to an upright position begun. After the scoop has been charged in the manner above stated, the direction of rotation of the drum 22 is reversed so that the scoop will be moved toward the left in Fig. 1 and at the same time the turning of the scoop around the shaft 13 is continued, so that by the time the scoop will be swung to the left into suitable proximity to the receiving hopper or car, it will also have been turned around the shaft 13 so as to discharge its contents into the hopper or car.

Provision is made preferably by means of a traveling belt, for the removal of the material from the receiving hopper or car, to a car whereby the material can be withdrawn from the point of loading. In the construction shown, a belt 48 of any 51 on the belt. The wheel is mounted in suitable bearings on the upper end of an upwardly inclined arm 52, projecting sucha distance in the rear of the loading truck or car as to permit the passage of the transfer car into position underneath its outer end. The wheel 50 is so constructed as to engage and move the carrying belt, and the shaft 5% onwhich. such wheel is mounted, has a sprocket-wheel keyed thereon, and around this wheel 55 and the driven sprocketwheel 56 is passed a chain 57. On the shaft of the wheel 56 is keyed a worm wheel adapted to be engaged by a worm 58 on the driving shaft 59. This shaft is driven by a motor (30 through a pinion and gear-wheel, as shown in Fig. l. 7

On the lower end of the shaft carrying the pinion 9, is keyed a beveled pinion 61, adapted to be engaged by oppositely disposed beveled gears 62 and 63, loosely mounted on the shaft 59 and adapted to be connected therewith b a clutch 64.

Provision is. made for shifting the entire loading mechanism. This. can be conveniently done by means of a sprocket chain 65, passing around sprocket wheels, one on the counter-shaft and the other secured to one of the wheels. On the counter-shaft is keyed 'a beveled wheel (36, adapted to be engaged by oppositely disposed pinions 67 and 68, loosely mounted on the shaft 59 and adapted to be connected clutch 70.

The scoop may be caused to move around tlie ishafl 10, through the material to a posithereto by a tion vo retain the material, and shifted arourd. the shaft 13 so as to maintain it in upright position during the discharging position. In order to hold the scoop in operating position, while being forged into the material to be removed, an arm .7111 is secured to one of the arms 11 in such position as to bear on a shoulder or.

abutment 72 on the scoop, when the latter is in receiving position, said shoulder being preferably formed on the flange 15.

It will be observed that the scoop is shifted radially as regards the axis of movement of the boom or outrigger, and that when swung to discharging position the material is dumped through the annular base of the boom, and the circular track on which the boom turns, is carried by the receiving hopper or car. This construction will permit. loading bein effected at any point in anarc of over 180 degrees.

I claim herein as my invention: 1. In a loading mechanism, the combination of a receiving hopper, an outrigger mounted on said hopper, arms pivotally conswing to 10 for moving said scoop in non-concentric arcs of circles having horizontal axes to gather material and discharge the same into the hopper, the axis ot one of th arcs being supported on the outrigger.

, t In testnnony whereot, J. have hereunto 15 set my hand.
